Decentralized Modelling of Data and Relationships in Enterprises

Modelling of data in enterprises is based on concepts like customer, supplier, order etc, and their fundamental relationships. Content and structure of these concepts must be standardised in order to support information flow between the different departements of a firm.Standardizaton is a very cumbersome process and results in a datamodell, which doe’s not reflect the special needs of decentralized business units. A decentralized datamodelling therefore will lead to similiar, but finally different concepts.In order to adapt the different contents and structures automatically, the differences must be known by machine. This may happen, if one restricts the modelling of data to a limited number of well known constructors, i.e. identification, generalization and spezification.
